By pressing the protruding buttons of the regulator to displace the support arms formed on both sides of the buttons and then drive respectively a turning body disengaging the chuck groves from the projection pieces of the band, the band can reach loosen state, in contrary the band can be constricted by pull the ends of the band while the protruding button free of pressure.

FIELD OF THE INVENTION

The present invention relates to a constriction assembly, more particularly, to a device used in face or eye mask, as well as swimming, sport or work mask etc, for adjusting the degree of tightness so as to control the tightness of their headband.

BACKGROUND OF THE INVENTION

As shown in FIG. 1, the traditional configuration of mask mostly at least includes an eye patch portion A that can comprise covering parts on nose, mouth or not, buckles B lying on both sides of the eye patch portion A and a band C provided between the two buckles B and having both ends D thereof connecting with the buckles B. By virtue of the function of buckles B and the operation on the ends D, the mask may be constricted on head. The said mask may further include various bands for tightening themselves on the objects to be constricted.

For example, the masks disclosed in U.S. Pat. Nos. 6,381,761 and 6,460,995B1 etc, all allow buckles to being evidently lying on both sides of the mask and at these positions the degree of tightness of headbands can be adjusted.

Operations on said configuration are very near the both sides of eye patch portion and it is not readily to operate simultaneously on both sides, so that problems, such as displacement of the eye patch portion and imbalance pressure often occur during operations. Therefore, try to improve operation manner and the configuration is an important task.

SUMMARY OF THE INVENTION

It is a primary object of the present invention to provide a constriction assembly of mask designed so that it is mounting on back of head etc, so as to have band easily provided on both sides of mask without the need to mount buckles having control and constriction function therein.

In order to achieve the above object the constriction assembly of the invention includes:

a casing seat formed into concave-shaped and having two opposite upward walls, an regulator held in the interior thereof and a base connecting a pad, wherein the upward walls having two opposite bores at the middle thereof for receiving protruding buttons of the regulator and two pairs of bores respectively at its both sides for mounting the tenon of turning body, and at its inside of the upward walls providing a round stick near the turning body on which two ends of band connected;

a regulator having opposite protruding buttons, wherein at both side of each protruding button provided with turning bodies while the turning bodies having a pair of tenons at its two transverse sides and chuck groves at the outsides thereof;

a pad underlying the casing seat;

two bands having ends mounting on the round sticks in the casing seat and the said ends provided with projection pieces;

a constriction configuration can be obtained when the state in which the ends tightly pulling the band achieved by the construct of said members; and that pressure on the protruding buttons makes support arms to move thereby the turning bodies are drawn movably around the tenons as axes by the support arms and then the turning bodies being in the state of lightly turning so that to make the chuck groves displace can form a disengagement operation of the chuck groves from the bands and further make the band loose.

The profile of the said casing seat presents arc shape.

The said pad is made of soft material.

The present invention assembly includes a casing seat that further has the function protecting the inside regulator from affecting by outside force or substance. The profile of the said casing seat may present flat smooth arc shape that not only reduces resistance but also gives its aesthetic feeling.

The present invention provides one pad between the assembly and head, wherein this pad may be made of more soft material and by which the pressure position on the head can be dispersed.

The regulator in the assembly can be made of material having deformable and flexible performance, such as POM, PVC, Silicone and Nylon.

The adjusting position of the present constriction assembly is apart from both sides of face mask. Therefore no large influence on the location of mask brought by the pull force exerted via the band and thus pressure on the face by the mask will be balanced.

The operation on the present assembly can be finished with single hand by two fingers' pressing on the button in the opposite direction and thus making the constriction assembly into loosen state, and exerting pull force on the two ends of the right and left bands can equably obtain the goal of constriction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 2, 3 and 4, the present invention mainly includes a casing seat 10, a regulator 20 and at least a pad 30 and two bands 40.

The casing seat 10 is primarily used to mount regulator 20 as well as fasten bands 40, and the base of casing seat 10 is connected to the pad 30.

The casing seat 10 includes a casing body 11 that has a general long receptacle profile and the casing body 11 be provided with openings 12 at the right and left side thereof as well as upward walls 13 on the front and back thereof. The upward walls 13 are provided with two pairs of bores 14, 14′ and another group bores 15, 15′ at the corresponding positions thereof, respectively, as well as opposite bores 16 formed on the middle thereof. There is provided a connection seat 17 at the low of the casing body 11 that connected to the pad 30.

The regulator 20 includes a group opposite protruding buttons 21, support arms 22, 22′ at the both sides of each button 21 and turning bodies 23, 23′ provided at the two outsides of the support arms 22, 22′. A pair of general co-axes tenons 24, 24′ are formed on two sides of turning bodies 23, 23′ that are provided with chuck groves 25, 25′ at the peripheries thereof.

The said buttons 21 are received in the bores 16 while the tenons mounting in the bores 14, 14′ such that the regulator can be installed into the casing seat 10.

The pad 30 made of soft material is secured under the connection seat 17 for the intention of being mounted between the present assembly and the object to be constricted thereby making the present invention assembly be comfortably utilized.

To provide a pair of round sticks 41, 41′ on the two-pair bores 14, 14′ is to allow the band 40 passing through. The band 40 is well-known member and is made of soft material that can have considerable elasticity and pliability.

As seen in FIG. 4, the present invention assembly is used in the biding condition on head.

As seen, FIGS. 5 and 6 show the deformation states of the regulator 20 in the present invention of the assembly while the protruding buttons 21 of the regulator under pressure, and FIG. 5 further involves partial members of the casing seat 10. The imaginary lines in the views indicate the deformation state with displacement. When the protruding button 21 bearing force to advance inwardly, the support arms 22, 22′ follows to make inward displacement and under this condition the turning bodies 23, 23′ are pulled movably by the support arms relative to the tenons 24, 24′ as axes by reason that the tenons 24, 24′ are mounted in the bores 15, 15′ of the upward walls 13, and the turning bodies being in slight rolling state. Therefore to make the chuck groves 25, 25′ displace is thus to make the band disengaging from the control of the groves 25, 25′.

As best seen in FIGS. 7 and 8, the bands 40 coil on the round sticks 41, 41′ and the two ends 42 of the band 40 are provided with some projection pieces 43. While the protruding button 21 being free of pressure, to see FIG. 7, the projection pieces 43 that are well known structure provided on the adjacent of band end are under the control of chuck groves 25, 25′ and then the band 40 can not move toward the direction of M in which the displacement can bring the band 40 to loosen state. However, since the band 40 formed with soft material, the movement that may result into constriction state from end portion 42 to the direction of N is contrary allowable, i.e. the end portion 42 can be pulled to control the tightness degree of band under the circumstance. When the buttons 21 of the regulator 20 are under pressure, as best seen in FIG. 8, the turning bodies 23, 23′ make rotary movement and the projection pieces 43 are not under the chuck groves 25, 25′ control anymore such that the constricted band 40 advances automatically toward the direction of M and then tend to the loosen state by oneself. In other words, in case the time pressing on protruding buttons 21 is very short that depends on the skillful degree of operation, the band 40 can be gradually adjusted on the degree of tightness; if the time is a little longer, the band 40 then can reach to absolute loosen state.

While there has been illustrated one of preferable embodiments of the present invention, numerous changes and modifications occurring to those skilled in the art do not depart form the scope of the present invention.

In conclusion, the present invention disclose features widely different from those in prior art either on the purpose, method or function, and it is practical i.e. which meet the requirement of utility, therefore it is appreciated that it will be granted after perceptive examination.
